Baby marsupials develop first in their mother's uterus. Inside the uterus is a yolk sac through which nutrients are given to the baby and through which wastes are released from the baby. After a few weeks (a much shorter gestation period than that of placental mammals), the baby has become more developed and is delivered.
What else can I help you with?
The young of which animal group crawl into their mother's pouch and stay until they're fully developed?
The young of marsupials are born under-developed and complete their development in their mother's pouch.
Is a kangaroo a monotreme?

What are Mammals that give birth to young at very early stage of development called?
These are marsupials, most of which then carry their young in a pouch while the joeys continue to develop.
Where do marsupial mammals complete their development?
After birth, most young marsupials, known as joeys, develop in the mother's pouch on her abdomen. Within the pouch, the teat swells in the young joey's mouth to help secure it in place. The joey remains in the pouch for up to nine months, depending on the species of marsupial. There are some exceptions to this: the numbat, for example, has no pouch. The young remain secured in place by the swollen teat in their mouth, clinging to the mother's underbelly.
Mammals that complete development out side of the body of the mother are called?
Mammals that complete development outside of the body of the mother are called monotremes, specifically referring to egg-laying mammals such as the platypus and echidna.
Does a koala have live young or eggs?

What is a marsupial sac used for kangaroos?

When you separate animals into groups what type would they be in such as marsupials?

Do male marsupials have pouches?

Do marsupials nourish their young with milk?

What do you call a young sugar glider?
